The Proxxon ring-open-end wrench is a high-quality tool designed for precise applications in various fields. With a size of 13 mm, it offers an optimal fit for many common screw connections. The wrench is made of robust chrome-vanadium steel and undergoes an elaborate surface treatment that makes it both nickel-plated and chrome-plated. This treatment not only provides an appealing appearance but also enhances durability and corrosion resistance. The polished heads are slim and thin-walled, allowing for easy handling in tight spaces. Additionally, the torque values of the wrench exceed the standards required by DIN/ISO, highlighting its reliability and performance. Each piece is calibrated and undergoes a final inspection to ensure it meets strict quality requirements.
